UNITED s'TATEs EEsILIEN'r WHEEL.

Specification of Letters Patent.

Patented Sept. 22, 1908.

Application filed February 4, 1908. Serial No. 414,230.

To all whom it may concern:

Be it known that I, JAMES E. MGQUILKIN, citizen of the United States, residing in the county of Westmoreland, near Apollo, Armstrong county, and State of Pennsylvania, have invented certain new and useful Improvements in Resilient Wheels, of which the following is a specification.

The object of this invention is an improved 'resilient wheel for vehicles that is designed to supercede the ordinary pneumatic-tired .wheel in which the tire is subject to abrasion,

F1 ure 1 is a longitudinal section of the hub and oxing of my improved resilient wheel; Fig. 2 is a transverse section thereof'on the line 2-2 of Fig. 1; and, Fig. 3 is a similar view of the inner portion on an enlarged scale.

kCorresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

My improved wheel is designed to be mounted on the spindle A of an axle, and embodies a'boxing' 1 journaled on said spindle and having its ends exteriorly threaded as indicated at 2. A hollow cylindrical hub 3 encircles the `entire boxing excepting the threaded ends 2 thereof and is spaced from said boxing as shown, said hub being preferably formed in its 'inner surface near its opposite ends with annular grooves 4 and in each groove with a plurality of o enings 5.

A resilient element is designe to be interposed between the boxing and the hub and in the present-instance comprises two pneumatic cushions 6 which fit in the s ace between the hub and the boxing and w ich are received in the interior grooves 4. Each cushion 6 comprises an inner or pneumatic tube 7 formed with an inflation valve 8 that rojects through one of the openings 5 in the ub and an outer tube 9 incasing the inner ed Shanks 10 which extend through the remaining openings 5 and have nuts 1 1 mounted on their ends, said Shanks serving to secure the cushion to the hub;

In order to hold the cushions securely to the boxing and prevent any movement relative thereto, tie-bands 12 are provided within the outer tubes 9 and are formed at their ends and at intervals intermediate of their ends, with lugs 13 which project inwardly through the outer tubes and are received in sockets 14 formed in the periphery of the boxing. Turn-buckles 15 are engaged with the end lugs 13 of the tie-bands 1n order to hold said ends adjustably together.

Cap-plates 16 are mounted on the threaded ends 2 of the boxing and arev designed to be screwed against the respective ends of the hub to prevent dirt from lodging in the space between the latter and the boxing, said capplates preferably extending outwardly beyond the hub in order to remain in an operative relation thereto during any vibration or the like of the wheel.

In the preferred construction of the hub, the latter is constructed in two sections 17 the adjacent ends of which have a telescoping connection and are formed with outturned flanges 18. The inner ends of the spokes 19 are tted between these flanges and are held rigidly in position to supporta suitable rim-by bolts 20 or the like passing through the flanges, said bolts also serving to secure to ether the two sections of the hub.

From t e above description in connection with the accompanying drawing, itwill be apparent that I have provided a simple, durable and efficient construction of resilient wheel in which the pneumatic cushion will not be subject to abrasion or the like as is the case with the ordinary rim tire.

Having thus described the invention, what I claim is:

1. In a wheel, the combination of a boxing formed in its eriphery with a plurality of sockets, a huid encircling the boxing and spaced therefrom, an annular cushion interposed between the hub and the boxing, a tie band carried by the cushion and formed with inwardly disposed lugs seated in the respective sockets of the boxing to prevent the cushion from rotating relative thereto, and means for rigidly securing the cushion to the hub.

2. A wheel, embodying a boxing formed tube and provided with a plurality of threadi in its periphery near each end With a pluralthe outer tubes and formed with lugs exten dity of sockets, a hub encircling the boxing l ing therethrough and received in the sockets and spaced therefrom, said hub being formed 1 in the boxing and ineens for securing tonear each end With a plurality of openings I gether the ends of the tie-bands. 1.3 extending therethrough, cushions interposed In testimony whereof I allix my signature between the corresponding ends of the hub in presence of two witnesses.

and boXinQr` and constructed in inner and f outer tubesJ a plurality of Shanks secured to JAMES E' MCQUUJRIN' [L' S'] the outer tubes and projecting through the f Witnesses:

openings in the hub With nuts mounted on l EARLE F. COOHRANE, their outer ends, tie-bands provided Withinl JNO. COCIIRANE.
